The night before the couple said “I do,” they were seen out having a date night at Loulou’s nightclub in London on Thursday – a gold ring was spotted on Eberstein’s wedding ring finger.

The surprise wedding comes just two months after the couple welcomed their third child together in March. The couple has not released details about their newborn, which is Grant’s fifth child. The actor’s ex, Elizabeth Hurley, accidentally let it slip that the private couple had added a new member to the family.

“I’m very lucky that 31 years into our friendship, he’s still my best friend in the world. He’s a really great guy,” Hurley announced on E!’s Daily Pop in March. “You know, he’s now a father of five; he has five kids and he’s a great dad. Yeah, he will remain my best friend for life.”
